For a positive integer,, we define N! (read N factorial) to
be the product of all the integers from 1 to N. Thus:
It is clear that N! will end in a zero if N is larger or equal to
5. For big values of N, N! will end in many, many zeros.
How many zeros will end in?

75/5 + 75/5² = 18.
Why did the vector cross the road?
It wanted to be normal.
